In Algeria, the aging of palms is a significant constraint, since 30 % of the palms are over the age of production and they will consequently waste planting areas. A series of experiments have been accomplished to observe the possibility of converting the date palm stem into valuable woodworking products. This paper reports the results of an experimental investigation on the physical, chemical and mechanical properties of date palm trunk (Phoenix dactylifera L.) from Biskra oasis in Algeria. First, their chemical composition was studied and showed that they have amounts of holocellulose, lignin and cellulose similar to those encountered in softwood and hardwood. Results of flexural strength showed that the modulus of elasticity (MOE) and modulus of rupture (MOR) were 6647.04 MPa and 35.04 MPa, respectively. The compression modulus and strength were 5.35 MPa and 2.338 MPa in parallel compressive tests, respectively.


In Algerien stellt die Alterung von Palmen eine signifikante Einschränkung dar, da 30 Prozent der Palmen über dem Produktionsalter liegen und diese vergeuden als Konsequenz Anpflanzungsgebiete. Eine Reihe von Experimenten wurde ausgeführt, um die Möglichkeiten der Nutzung der Palmenstämme für wertvolle Holzverarbeitungsprodukte zu untersuchen. In diesem Beitrag werden die Ergebnisse einer experimentellen Untersuchung der physikalischen, chemischen und mechanischen Eigenschaften von Dattelpalmstämmen (Phoenix dactylifera L.) der Biskra Oase in Algerien vorgestellt. Hierzu wurde zunächst die chemische Zusammensetzung untersucht und es stellte sich heraus, dass sie ähnliche Mengen an Holocellulose, Lignin and Cellulose wie Weich- und Harthölzer aufweisen. Die Ergebnisse hinsichtlich der Biegefestigkeit ergaben einen Elastizitätsmodul (modulus of elasticity (MOE)) und einen Bruchmodul (modulus of rupture (MOR)) von 6647.04 MPa bzw. 35.04 MPa. Der Druckmodul und die Spannung bei maximaler Festigkeit betrugen im parallelen Druckversuch 5.35 MPa bzw. 2.338 MPa.
